Up for sale is a used, manual focus Albinar ADG 28mm f/2.8 wide angle prime lens, serial #84202444, which has a Minolta MD mount and comes with both caps. The glass is in clean shape with no scratches or fungus present.  As with any older lens, there are some tiny specks of internal dust, but this won't have an effect on image quality.  Focusing is smooth, with close focus down to 8" for a reproduction ratio of 1:4; the diaphragm is likewise functioning smoothly with no oil on the aperture blades.  Cosmetically, the lens is in attractive overall shape with only light wear from age and previous use.  Please be sure to fully enlarge the provided photos, and feel free to contact me with any questions you may have.
